For IDXG, the catalst really work. The price went up for 2 days. No more catalyst showed up till now. I would like to wait and see. The supporting line is 0.8. Prefer not to chase the stock. Given the price may crash anyway.

For DXTR, recently the negative news is more than negative news. But the price spike yesterdayl. Weird price movement. I will not touch the stock, given the catalyst is not clear. 

The price may go down today given no catalyst support and the supporing price is 0.24. 

For DCTH, I can't find any catalyst for the stock, although the price just spike. Like IDXG, the price may crash anyway, given the price is low. It is not so much worth to short. I will keep observe the movement.

For GPRO and HMNY, the chart went down ugly in the second day. That mean the positive catalyst can not work for long time. I will leave this two stock alone, given lots of people would like to sell. Although short is a better approach, but there is no shares to short.
